I think that perhaps it's because I'm so tall -- I'm 6'1" -- that I always have cold feet.
That's my theory, anyway: That my blood doesn't have enough oomph! to make it all the way down to my feet and still retain heat, and so the poor circulation means that my feet are ALWAYS cold.
Which is a big problem for me. I mean, on the great ranking of problems it might not be so bad, overall, but I can't get comfortable: I have to wear socks all the time, or shoes, and who wants to sit around their house wearing SHOES?
Plus, even that's not so great a help: I'm wearing socks and slippers right now, and my feet are still a little cold, even though they're all dressed up with no place to go.
I mention this because I heard about these Volt Heated Slippers the other day and went to check them out. That's a picture of them over to the right there. They look sturdy, and they look warm, and they aren't just insulated and tall, but they have their own internal heater that's rechargeable.
Here's some things about that: I think as I consider this that the problem is that while I can wrap my feet up in as many layers of socks as I can find, that's not warming them up because my feet aren't generating their own heat. That's where this Volt idea comes in: they make their own heat, so it's like an electric blanket for your feet: instead of wrapping them up and hoping they warm up, I can just simply get them warmed up right away.
I've never used a rechargeable heating thing -- but I believe this might work, because I read about how the company got started and where the idea came from: The inventor, according to Volt's site, worked in the heated clothing industry making things for motorcyclists and the military -- two groups who would really need quality stuff-- and then tried to create a heated slipper in part for his mom, who had cold feet all the time and then saw her condition worsen when she developed neuropathy and was diagnosed with cancer. Rather than watch his mom use two heating pads to try to keep her feet warm, the inventor came up with the Volt -- which acted like a heating pad but which let his mom move around.
Hence, the Volt: a durable slipper that acts like an electric blanket for your feet, but lets you go inside and outside.
I don't know what really makes my feet so cold -- poor circulation probably is the answer -- but I'm willing to give these a try, because if your FEET are warm, the rest of you is probably doing okay.
